“Just wanted to say thanks for helping me with my experiments, Brighton. Really needed it,” Alkali said, hopping between his left and right feet happily. His kangaroo tail swayed just a bit behind while he rifled through stacks of papers on his desk. With how quickly this new job at the university had started up it was no surprise that things were disorganized. There was just one paper in particular he needed to find though.

Waiting in the roo’s office was a dingo wearing a sweater vest and khakis. “Well don’t worry about it. I know it’s hard to be a new researcher. You’ll pick up grad students soon enough though. Glad to help for now,” the Brighton replied. “What did you say you were planning to study again? I missed your talk during the interviews.”

The kangaroo had moved on from his desk into checking through file cabinets. “That talk was about biochemistry and the general uses for size changing. So ostensibly, the university thinks I’m here to study various ways to cause growth and shrinkage,” Alkali said before pulling out a paper and shoving it into the dingo’s hand. “But I want to be a little more varied than just that too. Magical artifacts, psychology, time travel. I have plenty of ideas. Ever read that manuscript before?”

Brighton looked down at the paper he’d been forcefully given. ‘On The Subject Of Living Vinyl.’ He’d read this paper several years ago, something written by an otter scientist if he remembered correctly.  Whatever that researcher was on about though had never really materialized. At least as far as Brighton was aware, there were no living pool toys walking around in regular everyday life.

“Sure. Interesting enough ideas in the paper. Made for a nice read. Why?”

“Because it works. Now hold still please,” the kangaroo answered. Brighton had no time to respond before he felt a small prick in the side of his neck. He recoiled reflexively, swatting at Alkali’s hand. A small device looking a bit like an epipen clattered to the ground. Brighton rubbed his hand at the spot he’d been stuck. It was tender to the touch, and a little bit… hard? The room started to spin and the dingo promptly passed out. The last image he could see before the world went dark was Alkali standing over him, with another set of beakers in his arms.

It took a bright light shining in his face to bring the dingo back to the realm of consciousness. He squinted and blinked to get used to the sudden harshness of the light. That didn’t seem to help much so he brought both hands up to his face to try and block his eyes. There was an odd lightness to the movement of his arms, but he just attributed that to the sensation of still waking up. Just as suddenly as the light came it dimmed as a figure walked in front.

“Sorry about that but I had to wake you up somehow. You’d been out for a few hours,” Alkali said cheerily. “The experiment seems like it was quite the success by the way. Thanks again for your help.”

Brighton’s was still a little loopy though. “Experiment? What? I just remember talking about pool toys and then passing out.”

“Oh right. That makes sense. Maybe it’d be easier for me to just show you the results rather than bore you with the details,” Alkali said as he produced a mirror. Brighton still wasn’t sure what had happened. He felt light, lighter than usually, like he was in the middle of a flying dream that he hadn’t woken up from. The dingo reached out to take the mirror and realized something else was wrong. Namely, his fingers. The fact there didn’t seem to be any on his hand was mildly concerning. Just as much as the fact that hand looked something like a mitt, almost like on a child’s toy. It still flexed like normal though so he was able to reach the mirror and take a look.

As soon as he looked the dingo yelped and dropped the mirror, not recognizing whoever was in it. He looked like a pool toy; with functioning mouth and muzzle and arms and legs sure, but definitely a pool toy. He’d been stripped naked with a still visible set of genitals thank goodness. But right above that at his tum was a little valve.

“Awww why’d you drop the mirror? I liked that thing. Still haven’t figured out the enchantment on it yet either,” Alkali mumbled while picking up the pieces of the glass.

“B-Because… who was that!? That wasn’t me was it?”

The kangaroo stood up again and looked genuinely puzzled. “You? Well yeah, it’s you. That wasn’t the experiment though. I already knew the pool toy serum would work just fine. Tried it out on a few friends before after all. You must not have gotten a close enough look.”

“I’m a pool toy now? Alkali, you need to change me back! I have a class to teach- wait. This wasn’t the experiment? Then what was?” the dingo toy squeaked.

Brighton tried to pull himself forward off the medical table and found strangely that this time there was some extra weight to it. Which was strange considering that pooltoys should be filled with air. Pushing himself up into a sitting position he realized just why that might be; he wasn’t filled with air after all. At least not entirely. Filling up nearly half his body was a strange pink liquid. It wobbled and sloshed back and forth inside his legs and up toward his slightly bulging belly.

“Oh, careful there. All that daiquiri is going to take some time to get used to moving with there buddy,” Alkali said, setting a hand on Brighton’s shoulder.

The dingo kicked his legs back and forth as they dangled. “Daiquiri? Alkali, just what did you do to me?”

“Your body produces daiquiri at a slow rate now, slowly filling you up. It’s an idea I’d wanted to test out for a long time, to see if it were possible to make a living keg of sorts. Geo is the one who suggested the daiquiri though,” Alkali said, giving his friend’s belly a swat. It wobbled back and forth before the roo held it in place with a squeeze. “So you’ll need to be a little careful with your body now. You won’t pop, I made sure of that. But if you want to fit places you’ll need to ahh, let off some pressure every so often. Geo can help you with that I’m sure.”

If Brighton hadn’t already been blushing, now he definitely was. “O-Ohh. Ahh. That sort of pressure release huh?” Suddenly remembering that he was naked, the living vinyl dingo put his mitts in front of his crotch to try and hide the slowly chubbing up shaft as it filled with the strawberry flavored alcoholic drink.

Alkali grinned brightly. “Yup. That kind of release. Which I’m sure Geo will very much enjoy getting drunk off. Sort of like getting a flavored cum shot eh?”

“A-Alkali, cut it out!”

“Fine fine, sorry. I’m just happy the experiment worked that’s all.” Alkali sure didn’t seem sorry though, hopping back and forth. A small buzzing from the corner interrupted their discussion. It was Brighton’s phone with a small clock on the screen and a reminder. ‘LECTURE IN 15 MINUTES’ it said.

“Oh god, what time is it? How long was I asleep?”

“It’s almost 2:45. Had to put you out for-”

“Alkali! Shoot. Help me get my clothes on, I need to get out of here,” the dingo said, waddling and stumbling his way over toward the pile of clothes. It took a few minutes to get all his clothes on while still working the new hands, and pulling them up on a squeaking, furless body. But eventually he did get to some facsimile of being decent.

“Wait, Brighton, I haven’t told you any of the details of how the experiment works. Just wait and-“

But the dingo was already running out the door with his liquid insides wobbling massively. If anyone was giving the walking, panting pool toy any strange looks he couldn’t be bothered. More important at that moment was being sure he got to his class. The students were counting on him, and his job depended on it. Brighton rushed through the door before trying to skid to a stop. It was more like he tried to stop and the momentum from his sloshing alcoholic body didn’t quite respond how it should, propelling him forward into the lecture hall’s computer.

A few voices in the crowd of students snickered. A few more gasped. But most were simply speechless, dumbfounded by the creature in front of them. Sure it wore the same sweater vest, khakis, and glasses. But it had no fur, and there was something flowing inside it.

“Uhh. Uhm. Good afternoon class. I hope you don’t mind my slight tardiness. There was something important I needed to attend to with a fellow professor. One of the new faculty in fact. But if you’ll just give me a moment to pull up my Powerpoint we can get started right away,” Brighton said, still trying to project an air of professionalism. The giggling seemed to have died down. Maybe this could work after all.

“Professor. Your sweatervest. It’s kinda… riding up on you,” a feminine voice from the back said, just loud enough so everyone in the hall could hear. His ears perked and he looked down. Sure enough, a tan tummy and belly valve could be seen just under the maroon and grey shirt. His face somehow flushed a bright red as he attempted to pull down on the sweater vest. No luck though; his belly was simply too bloated for his clothes to fit well anymore. The snickering returned.

The dingo looked back up and squeaked indignantly. So much for professionalism. “Yes, I’m sure you’ve noticed something different about me today. But not to worry, I’m still perfectly capable of giving a lecture to you. Science stops for nothing after all. Today we’ll be talking about…”

By the time he was finished with his lab work for the day Brighton was finding it increasingly difficult to deal with the stresses of his new body. The movement part had solved itself mostly, thank goodness. A few hours worth of walking practice had seen to that. But there was no getting around the fact that his clothes didn’t fit at all anymore. They were meant for a body type at least a few sizes smaller. He’d need a set of XL, possibly XXL clothes to fit anymore. His pants were ripping, his sleeves only made it partway along his arm, and his belly was perpetually on display for the whole university.

Every minute that passed he could feel his body gurgling and filling still further with the beverage that had replaced his innards. True to his word, Alkali had made sure he would never pop; Brighton never felt tight, overfull, or the telltale signs of creaking. Instead his body just seemed to produce more vinyl to stay intact. To that end his gut had bloated, his thighs thickened, and height increased too. Despite all that extra space, it still wasn’t enough. A good eighty percent of his body was filled with the strawberry flavored daiquiri, turning his brown and tan translucent form a primarily pink tone. It was harder to move his arms now that they’d been filled up. On occasion a bit of it would splash up into his hollowed out mouth and tongue so that he could enjoy the tasty liquid. At least there were small benefits to all this. The one thing he was more worried about than the lack of clothes and embarrassment was what would happen when he filled entirely. Alkali hadn’t mentioned any cure for what was happening. And if he was truly unburstable, would his height change only increase? Would there be any clothes left that could fit if his belly was truly enormous?

Finally the day was over and he could make his way home though. And not a moment too soon either. The nine foot tall dingo was starting to worry if he’d need to take the ‘pressure release’ into his own hands. His dick had apparently responded to the increasing internal pressure, staying at a pleasant half-chub all day long. That made movement even harder too. By the time he made it home he was pent up and teased to hell. The clothes came off immediately.

A small raccoon greeted him from the kitchen before walking out. “Briiiighton, how’re you chap? I- oh. You must’ve had a long day at the office. What happened?” Geo asked. The sway in his tail betrayed at least some interest in what was going on, but Brighton could tell it was mostly confusion right now.

“Nope, no time to explain. I need to get some pressure released. And a certain kangaroo told me earlier this choice was at least somewhat your fault. So hope you picked a good liquor for yourself. How drunk do you feel like getting tonight?” the dingo said. His hardened shaft was already preing slightly, daiquiri leaking out his vinyl tip like a dripping faucet.

The raccoon wasn’t one to look a gift dingo in the mouth. And together, it was a long night of drinking and debauchery.
